We've gone on about maximizing small spaces with clever ideas such as putting storage in unexpected places, like under the stairs or the bed. When these ideas become reflexive, some push the creative envelope even further, like in this quirky renovation of a tiny 400-square-foot apartment that features a catwalk and other surprises. Watch the silent video tour:

Done by Joseph Chiarucci of Fort Design Build for photographer Brendan McInerney, the apartment has a tall ceiling that allows for a kitchen and sitting area to be placed on the ground level, and a sleeping loft, bathroom and a storage loft to be built upstairs. There are small partitions judiciously placed in the small space, giving more surface area to add a corner desk.

The storage loft is accessible by the stairs and a catwalk, which may ruffle some safety-minded people out there (a handrail might be a good idea) but for Brendan, a passionate skateboarder, it's something he seems quite comfortable with.

The sleeping loft looks quite comfy with a secondary sitting area and a bed tucked in the corner. Underneath the bed are long, custom-made drawers that keep clutter tucked away. The bathroom is minuscule, but has a window framing the storage loft.

Then, here's where it gets a bit strange: there's a hole in the wall that gives access to a vacuum hose. With the flick of a switch, it's on and Brendan can tidy up. We suppose it's the micro-DIY version of a central vacuum system, and it's admittedly quite clever, as it hides the bulk of a vacuum within the wall.

This balance-testing apartment might not be for everyone, but you've got to admit, it's a neat example of how small spaces can be creatively used to express one's daring personality. To see more, visit Fort Design Build for photographer Brendan McInerney.
